SUMMARY
A description is given of a cavputer_program
• (GRAV3) used for calculating the gravity anomaly due to a
finite prism. The program is written in FORTRAN IV for
interactive use with an HP 21MX mini-computer and GOULD 5000
printer/plotter under RTE II using TEROS.
The program may be compiled, loaded, and executed
using a system teletype.^Little or no data preparation is
required and interpretation is achieved by forward
interactive modelling.
The program provides a computer plot together with
suitable annotation and a cross-section of the case
• modelled.
1.^INTRODUCTION
In metalliferous-exploration the need commonly
• arises to interpret gravity anomalies which are caused by
tabular bodies of finite strike length. The horizontal
prism of trapezium cross-section provides the interpreter
with a simple yet realistic geometrical form for a first-
order interpretation of an anomaly.
A computer program is described for calculating
the gravity anomaly of a finite homogeneous horizontal
prism. The program is called GRAV3 and is based on formulae
derived by Hjelt (1974).
The program has been written in FORTRAN IV for
interactive use with an HP 21MX mini-computer and a GOULD
5000 printer/plotter under RTE II using TEROS., The basic
program algorithm is simple and rapid, and could be readily
adapted for use with some of the more recent desk top
• calculators.^Little or no data preparation is required,
and interpretation is achieved by forward interactive
modelling.

2. CO-ORDINATE SYSTEM AND FORMULAE
Co-ordinate system
A rectangular co-ordinate system is used (Fig.1)
with the X axis perpendicular to the strike direction, the Y
axis parallel to the strike, and the Z axis positive
downwards. The dipping surfaces of the prism are defined
by the angles c and G. A special case of the model is
that of a prism in which C^e . The top and bottom faces
of the structure are horizontal, and the two faces
perpendicular to the strike direction are vertical.
The corners of the prism are defined by their
X,Y,Z co-ordinates (e.g. Xl, Yi, z1) and the distances
between the prism and the observation point P(X, Y, Z) are
denoted by U, V, and W as shown in Figure 1.
Oblique profiles
Profiles, other than those normal to the prism
strike, can be run by defining a profile co-ordinate system,
at an angle a to the prism co-ordinate system (see Fig.lb). In such cases, program GRAV3 plots the calculated
gravity values with respect to the profile co-ordinate
system.

The gravity anomaly of a prism with a more general•^trapezium cross-section is obtained by substituting 8 for E1
when U = U(2)or u(2) (see Fig. 1)

3.^PROGRAM DESCRIPTION
Flow chart
The essential elements of the program structure are shown
in the flow chart (Fig. 2)r .^Program variables used in the flow
chart are defined in the program listing (see Appendix). For
operational convenience in BMR, a number of system subroutines are
used, but these do not detract from the generality of the basic
program algorithm. System subroutines are referred to by name
(e.g. RMPAR, NUMB, etc.) and further details may be obtained from
the HP-RTE II system manual and the GOULD printer manual.
Data input
The input model parameters used in the program are
defined as follows:
MN^= Model number.^Always start with MN = 1
XI^= X co-ordinate of top edge nearest origin
X2^= X co-ordinate of top edge farthest from origin
YI^= Y co-ordinate of top edge nearest origin.
Y2^= Y co-ordinate of top edge farthest from origin
Zl^Depth to top of prism
Z2^= DepLh to base of prism
XN^= X co-ordinate of first observation point
YN^= Y
ZN^= Z
DX^= Station increment along X axis
THETA = Dip of prism edge nearest to origin in degrees
ETA^=^u^farthest from origin in degrees
BETA = Angle between X axis and profile, measured clockwise
from the positive X axis in degrees
DEN^r. Density contrast
NXN^= Number of stations

5.
The program is structured for maximum interactive use by
the interpreter, and may be compiled, loaded, and executed by means
of a system teletype. Model parameters for each case are fed to
the computer using a free-field format.
The source program is stored as a resident disc file
GRAV3S but is also available on paper tape.
Loading the program
To load the program, the following command sequence is
observed:
1. *GF, GRAV3S^This command calls the source program
into the user scratch region.
2. *FT, FL^This command causes the program to be
compiled as a binary relocatable file.
3. *GF, STAT..
^
^This command schedul.es the binary file
for loading.
4. *LD, 0^ This command causes the program to be
loaded.
The above steps are once-only commands and need not be
repeated while the system is up.
Running the program
To run the program, the following command sequence is
observed:
1. *LG, GRAV3^This command causes scheduling of the
program for execution.
2. "MN, X1, X2, Y1,^At this request, type in the appropriate
Y2, Z1, Z2 = "^model parameters.
3. "XN, YN, ZN, DX,^Type in appropriate parameters separated
NXN, DEN, ETA,^by a comma.

4. "MISTAKE IN INPUT^Answer YES or NO. If YES, the program

6.
•
•5.^"ANY MORE CASES?"^Answer YES or NO. If YES, the program
will return to step 2 so that additional
cases can be modelled.
The user may log into the program any number of times
using the command *LG, GRAV3.^User commands are preceded by a * as
shown;^terminal replies are given in inverted commas.
An example illustrating the use of the input commands
given in Figure 3.
If more than one case is to be modelled, only the
parameters to be varied need be changed.^For all parameters
preceding those to be changed, type in commas. Following
parameters may be ignored.
Data output
Two modes of data output are utilised. The calculated
gravity values are sent to the user teletype for immediate perusal
(Fig. 3) and also to the line printer for plotting. The graphical
plot includes suitable annotation and a cross-section of the case
modelled (see Figs. 4 and 5). A cross-section of the model is not
produced for oblique profiles.
4. PROGRAM TESTING
The program was tested against Nagy's (1966) formula for
the gravity effect of a right rectangular prism and with one of
Hjelt's (1974) cases.^The results shown in Figure 4 indicate an
excellent fit between the GRAV3 results and the test data.
